In this work, a transient three-dimensional nonequilibrium CFD solver HiSCFOAM-NonE is developed in OpenFOAM platform to accomplish the computation of hypervelocity reacting flows involved in high Mach number scramjet engines. Based on the theory of thermo-chemical nonequilibrium flows and the compressible solver rhoCentralFoam in OpenFOAM, this solver is designed to broaden the capability of the present CFD simulations by incorporating a two-temperature model which describes the nonequilibrium energy relaxation. In this regard, this solver is capable of simulating thermo-chemical nonequilibrium flows in scramjets operating in wide flight Mach numbers up to 15. Compared to the currently available open-source solvers, the HiSCFOAM-NonE solver is more robust and efficient by virtue of the introduction of the Mutation++ nonequilibrium thermodynamic package. The validity of this solver is evaluated by a set of elementary tests including zero-dimensional heat bath, high Mach number cylinder flow as well as complex shock-dominated flow in a model scramjet engine. Results show satisfactory accuracy compared to the currently available experimental data.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/05\/HiSST-2024-78.pdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Kun WU, Yu AO, Yuting JIANG, Jianwen LIU, Xuejun FAN<\/b><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: HiSST-2024-078<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1409,1407],"tags":[492,1126,1517,1518],"class_list":["post-16779","post","type-post","status-publish","format-standard","hentry","category-events","category-high-speed-aerodynamics-and-aerothermodynamics-11-hisst-2024","category-11-hisst-2024","tag-numerical-simulation","tag-scramjet-engine","tag-thermal-nonequilibrium","tag-two-temperature-model","category-993","category-1409","category-1407","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16779","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=16779"}],"version-history":[{"count":2,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16779\/revisions"}],"predecessor-version":[{"id":20998,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16779\/revisions\/20998"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16779"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16779"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16779"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
